Approximate minimum BER power allocation for MIMO-THP system [PDF]
, 2008 This paper proposes a transmit power allocation (TPA) scheme based on multiple-input multiple-output (MIMO) Tomlinson-Harashima precoding (THP) structure, where a TPA matrix is introduced to the conventional MIMO-THP.

Modeling of wide-band MIMO radio channels based on NLoS indoor measurements [PDF]
, 2004 In this paper, we first verify a previously proposed Kronecker-structure-based narrow-band model for nonline-of-sight (NLoS) indoor multiple-input-multiple-output (MIMO) radio channels based on 5.2-GHz indoor MIMO channel measurements.

IET Networks, EarlyView., 2023 We utilise a metaheuristic optimisation method, inspired by nature, called the Lévy‐flight firefly algorithm (LFA), to tackle the power regulation and user grouping in the NOMA systems. Abstract The non‐orthogonal multiple access strategies have shown promise to boost fifth generation and sixth generation wireless networks' spectral efficiency and ...

A line-of-sight optimised MIMO architecture for outdoor environments [PDF]
, 2006 The authors present an investigation on the capacity of Line-of-Sight (LoS) optimised and conventional (narrow-spaced) Multiple-Input Multiple-Output (MIMO) communication systems in outdoor environments. Under a LoS scenario, the channel is normally rank
